Answer:

$15.44

Step-by-step explanation:

Answer:

about 101.22

Step-by-step explanation:

The answer is B. If angle b is congruent to angle c, then you would write the problem as 12x + 4= 14x-2. X=3. You can check by substituting three for x.

Final answer:

To find the value of x in the isosceles triangle ABC with given angle expressions, we set the expressions for angles B and C equal, leading to a simple equation that yields x = 3.

Explanation:

The question involves finding the value of x in an isosceles triangle where the angles at base B and C are given as algebraic expressions in terms of x. Since triangle ABC is isosceles with angles at B and C being equal, we can set the expressions for m∆B and m∆C equal to each other and solve for x.

Let's set up the equation using the fact that m∆B = m∆C since ∆ ABC is isosceles:

(12x + 4)° = (14x - 2)°

We can then solve for x:

Subtract 12x from both sides: 4° = 2x - 2°

Add 2° to both sides: 6° = 2x

Divide by 2 to solve for x: x = 3

The value of x is therefore 3, which corresponds to answer choice B.

Answer:

A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides. A square has two pairs of parallel sides, four right angles, and all four sides are equal.

Step-by-step explanation:

the equation of the graph  : y = sin(x + 90°)

because when :  x= 0 :  y = sin90° = 1

Answer:

Option A y = sin ( x + 90 )

Step-by-step explanation:

The given graph is the graph of cosine which should be in the form of

y = a cos ( bx + c ) + d

here a = amplitude = [tex]\frac{1-(-1)}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

Since period of the wave is 2x or 360°.

we know, period = [tex]\frac{2\pi }{b}[/tex]

                          [tex]b=\frac{2\pi }{2\pi }[/tex] = 1

Now equation becomes,

y = cos ( x + c ) + d

In this graph there is no horizontal or vertical shift

c = 0 and d = 0

so equation will be  y = cos (x)

as we know              y = cos (x) = sin ( 90 + x )

Therefore, Option A y = sin ( x + 90 ) is the answer.

Answer:

Three angles, measuring 25,65, and 90.

Answer:

your answer would be 9 printers

The answer is:

There are a total of 9 black and white printers

To solve the problem, first, we need to calculate how many color printers represents two-fifths of the total printers, then, calculate the number of black and white printers using the total number of printers and the number of color printers.

Calculating how many color printers does the departament have:

[tex]ColorPrinters=TotalPrinters*\frac{2}{5} \\\\ColorPrinters=15*\frac{2}{5}\\\\ColorPrinters=\frac{30}{5}=6[/tex]

Therefore, we have that there are 6 color printers.

Now, calculating the number of black and white printers, we have:

[tex]TotalPrinters=ColorPrinters+BlackAndWhitePrinters\\\\BlackAndWhitePrinters=TotalPrinters-ColorPrinters\\\\BlackAndWhitePrinters=15printers-6printers=9printers[/tex]

Hence, we have that there are a total of 9 black and white printers.

Answer:

312 m

Step-by-step explanation:

Write and solve an equation of ratios:

 7       273 m

----- = ------------

 8            x

Then 7x = 8(273 m) = 2184 m

and x = 2184 m / 7 = 312 m

The second length in the given ratio of 7:8, when the first length is 273m, is calculated to be 312m.

The given question is about ratios, particularly the ratio between two lengths, where one of them is given as 273 meters and the ratio is 7:8. The ratio tells us that for every 7 units of the first length, there are 8 units of the second length. To calculate the second length, first find the value of one ratio unit by dividing the given length by its ratio (273m / 7), then multiply your result by 8.

Steps:
1. 273m / 7 = 39m (This is one ratio unit)
2. 39m * 8 = 312m (This is the second length).

Therefore, the length of the second line is 312 m.

The angle between the longest side and the diagonal of the rectangle is approximately 30 degrees.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

To solve this problem, we can use the Pythagorean theorem and trigonometric functions.

First, we can find the length of the diagonal of the rectangle using the Pythagorean theorem:

diagonal² = longest side² + shortest side²

diagonal² = 1000² + 577²

diagonal = √(1000² + 577²)

diagonal = 1162.46 mm (rounded to two decimal places)

Next, we can find the angle between the longest side and the diagonal using the inverse tangent function:

tan(θ) = opposite / adjacent

tan(θ) = 577 / 1000

θ= arctan(577 / 1000)

θ= 29.98

θ ≈ 30 degrees

Therefore, the angle between the longest side and the diagonal of the rectangle is approximately 30 degrees.

To circle all values with a z-score greater than 0.5, calculate the z-score for each value and compare it to 0.5. The values with a z-score greater than 0.5 are 76 and 78.

To determine which values have a z-score greater than 0.5, we need to calculate the z-score for each value in the data set. The z-score formula is calculated by subtracting the mean from a value and then dividing by the standard deviation. If the resulting z-score is greater than 0.5, we circle the corresponding value.

Based on the calculations, the values with a z-score greater than 0.5 are 76 and 78. Therefore, these two values should be circled.

To find the relationship between two quantities, x and y, in a table, analyze patterns in the changes of the values, determine if the relationship is linear or nonlinear, and then use the identified relationship to calculate missing values. A computer can be useful for plotting data and visualizing the relationship.

To find the relationship between two quantities, x and y, in a table, first, you need to look for a pattern in the way the numbers change. If y changes by a consistent amount when x changes by a set amount, the relationship is likely linear. If the rate of change itself changes, the relationship may be nonlinear. To determine the relationship:

When calculating these relationships, plotting data using computers can be helpful, especially for identifying linear or nonlinear relationships and for regression analysis in more complex datasets.

Tara's unit rate of reading is 1.4 pages per minute, which means an equivalent rate is 2.8 pages per 2 minutes.

The question involves calculating an equivalent rate to Tara's unit rate of reading pages per minute. To find Tara's unit rate, we first need to determine how many pages she reads in one minute. Since Tara reads 3 1/2 pages in 2 1/2 minutes, we divide the number of pages by the number of minutes to find the unit rate:

To find an equivalent rate, we can multiply both the numerator and the denominator by the same number to get a rate with different terms but the same value. For example, multiplying by 2 would give us:

Therefore, an equivalent rate to Tara's reading speed would be 2.8 pages per 2 minutes.
